STOP-MOTION `FOR, SPEEDERS.

`Specification of Letters Patent No. 111 ,l-7 5, dated August 8, 1854.-.

To all 'whom t may concern.'

Be it known that I, Lewis Corriere, `of

Lowell, in the county of "Middlesex and State of Massachusetts, have invented cretain new and useful Improvements in the Stop- Motions of Speeders, Stretchers, Slubbers, and Fly-Frames; and I do hereby declare the following to be a full, clear, an'd exact description of the samerreference being had to the accompanying drawing, making a part thereof, and which represents a perspective view of the several operative parts.

As heretofore constructed,`no friction or` guide,'has been placed or applied between the can and the trumpet of this class of machines, and the unequal lifting of the lap or sliver from the can, often produces a slack, which allows `the trumpet to fall and throw off the belt, even when the sliver has not broken or run out. This arises from the fact thatthe weight alone of the sliver, it being very inconsiderable, is not suiiicient toA hold up the` trumpet. `Another difficulty with the stop motions as. at present used, that when the lap or sliver does break or run out, the shipper is not brought into action with the necessary certainty required, nor does it operate instantaneously. This evil produces another, viz: the winding or tangling of the thread or sliver around the fliers, it requiring much more time to strip i or wipe the fliers, than to unite the broken thread `or sliver.

The object of my invention is` to remedy the above named defects, and consists first, in the interposition between the can and the trumpet of a guide or ring, for the purpose of producing `friction suflicient in connection with the weight of the lap or sliver, to insure the holding up of the trumpet, and not depending solely upon the lifting of said sliver, which is variable, and I would state in this connection that guides have been used on the other side of the trumpet, orbetween it and the rolls or iiy frames. This is no part of my invention.

` The second part of 'my invention relates to the means for more certainly and instantaneously tripping of the shipper when a sliver breaks or runs out, and consists in the substitution of a very light lever, rod or wire, the weight of which merely is to be lifted, and to do this the trumpet need not fall or move more than an inch, and may be quite light, while in the other forms the trigger must be moved against the `action of one `or more springs, and the trumpet have sufhcient poweror force to rock a shaft for the tripping of the shipper.

My invention may therefore be summed up as follows, first, to prevent the throwing olf of the belt, by any other cause than that of the sliver breaking or running out, and second, that when it does break or run out, the belt shall be instantly thrown o To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

The can from` which the sliver is taken may be placed immediately under the guide or ring A, said sliver first passing through said guide or ring, and thence through the trumpet B, to the rolls C. The friction in the ring or guide causes the trumpet to stand up, while without it the sliver would sometimes be raised unequally from the can, and cause a slack therein, which would admit of the trumpets falling, and tripping the shipper without the breaking or running out of the thread.

A lever D, which may be a light wire, is hinged at l, and plays between guides 2, said lever and guides being attached to a plate E, projecting 'from the frame F. The trumpet wire G, is so bent as to pass through the lugs 8 on said plate E, and terminates in an arm 4:, which when the trumpet drops,`

lifts up the lever I). A

H, is a rock shaft, having at one end the rod I projecting downward, and at the other end an arm J,projecting upward. A lever or rod K, connected by a wrist pin to the rolls C, `passes through a slot in the arm J, and is hollowed Vout at that point, as at 5. A chain 6 connects the lever K, with the catch L, which holds the shipperM, against the action of the helical spring 7 around it. When the lever D,is down the arm I, passes over, but when raised up this arm strikes it, throwing up the rod K, forcing its depression 5' out of the slot in the arm J, and by means of the chain 6, lifting the catch L. The catch L, being released the helical spring 7, immediately throws the shipper M, which runs oif the belt. To perform these movements the lever D need only be raised from a sixteenth to an eighth of an inch.

Having thus fully described the nature of hinged lever, the interposition between the can and trumpet of a guide so arranged as to give suicient friction to the roving when it rlses irregularly from the can, to prevent the dropping of the trumpet and consequent throwing ofi of the belt, substantially as de scribed.
